-
- you can't using the getty that was supplied with 386bsd 0.1.

- the problem with the getty supplied is that it uses the old v7 tty
- interface (struct sgttyb). but just before it exec's a login it sets
- "defaults" using the newer termios-functions. thus, you never get any-
- thing else than 7e1!
-
- i've hacked getty to use termios instead of sgttyb, but not all of the
- things that can be configured using gettytab have been coded in getty yet.
- the main problem with that is that there are some values in the sgttyb
- structure which can't be converted that easily.
-
- actually i think the best way would be to hack or port a system v-getty
- clone to 386bsd instead of using the kind of outdated gettytab file,
- unless you add a lot of new parameters to gettytab. i haven't done either,
- but if anyone wants/needs a getty desperately that's able to set
- the line to 8n1, 7e1, by gettytab configuration flags i could mail it.
-
- but beware: this is currently a hack that works for me, but the work
- is still far from being finished.
-
- so long,
- felix
